Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide:

Question

CaO(s) + H2O(l) �¨ Ca(OH)2(s)
In a particular experiment, a 2.00-g sample of CaO is reacted with excess water and 2.14 g of Ca(OH)2 is recovered. What is the percent yield in this experiment?

Answer 1

You must first determine the theoretical yield. Here is an example. Just follow the steps. http://www.jiskha.com/science/chemistry/stoichiometry.html
The %yield = (actual yield/theoretical yield)*100 = ??
